RE: TRACE used to increase the dangerous of XSS.

Isn't this a bug in Internet Explorer? Shouldn't the Microsoft XMLHTTP ActiveX control be removing cookies from returned HTTP headers when a HTTP TRACE is done? I know that this already happens when a GET or a POST is done with XMLHTTP.

Subject: TRACE used to increase the dangerous of XSS.

WhiteHat Security has released a new white paper discussing a new class of web-app-sec attack (XST) which potentially affects all web servers supporting TRACE.

The white paper explains all the detailed technical results we have found so far. We are fairly certain this particular issue will spark much debate and encourage those interested to read and comment.
